ROBLOX completely removed the old saving system. Do not buy anything as it won't save. All items are now too expensive to buy until the game is updated someday. For those of you wondering why this game looked quite funny in that video, I did not spend that much time creating it (around 20 hours on coding/animations) a few years ago. I'm currently working on an entirely new version that will hopefully be released in the summer. I'll continue working on it after my final exams in June. https://www.roblox.com/games/262068610/FPS-system-In-development
This game does not support Private Servers.
